EJECTOR FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 685,233, dated October22, 1901.

Application filed May 16, 1901. Serial No- GOASS. memorial.)

To all whom it may concern:

Be it known that I, ALBERT H. DAY, of Mohawk, in the county of Herkimerand State of New York, have invented certain new and useful Improvementsin Firearms; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the charactersof reference marked thereon, which form part of this specification. I

The object of my present invention is to provide a new combinationextracting and ejecting mechanism for firearms.

Figure l of the drawings shows a perspective view of the operative partsof a firearm, including my extractor-ejector, certain parts being brokenout to expose the mechanism. The parts are shown in the positionimmediately following the firing of the arm. Fig. 2 shows in a similarmanner the same mechanism substantially at the end of what may be termedthe first stage or portion of the eX- tracting and ejecting movement.Fig. 3 shows a cross-section of the mechanism, including the frame ofthe arm, substantially at the rear end of the barrel. Fig. 4 shows inperspective in'a similar manner to Figs. 1 and 2 the same mechanism inits final position after extracting and ejecting the shell. Fig. 5 showsa perspective view of the breechblock removed from the arm.

Referring to the reference characters in a more particular descriptionof the device, 1 indicates the barrel, and 2 the receiver or frame, towhich the barrel is attached. Pivotally mounted on a transverse pin 3,passing through the frame, is the breech-block 4, adapted to move orswing from the position shown in Fig. l to that shown in Fig. 4. The

hammer 5 is mounted on a pivot-pin 6, also passing transversely throughthe frame. The hammer 5 is provided with a shoulder 5*, adapted toengage the rear of the breechblock and secure the same in firingposition.

The extractor and ejector, which is the feature of my presentinvention,is a washer-like l piece 7, having a comparatively large central openingand mounted on the cam or eccentric hub or boss 4 of the breech-block.The hub or boss P is arranged with reference to the breech-block so thatthe throw position of the eccentric is over or above the pivot 3 Fig. 1.

engage with the cartridge A, and is also provided with a wing-likeportion 7*, having two straight faces 7 and 7 arranged at an obtuseangle with reference to each other, substantially as shown. Secured inthe lower portion of the frame there is provided a spring 8, adapted toengage with the faces 7? and? of the extractor-ejector. The wingportion. of the extractor-ejector is also provided with a slottedopening 7, which has a peculiar arrangement with reference to the restof the parts, as will hereinafter appear. This opening 7 is adapted toreceive the inwardly-projecting end of a screw 9, secured in the frame.The lower wing-like portion' 7. ofv the extractor ejector is thickerthan the upper portion of the same, as ap pears from Fig. 3 of thedrawings, whereby the'lower wing-like portion is confined againstlateral movement between the wall of the frame and the side of the lowerportion of the breech-block 4E. The upper portion of the part 7 acts aspring and has a limited amount of lateral play on the hub or boss 4:,as is also apparent from Fig. 3 of the drawings. 1

The operation of the device-that is to say, the extractor-ejector moreparticularly-is as follows: Starting with the parts in the position inwhich they are shown in Fig. 1 immediately following the firing, thecatch 7 of the part 7 is found engaged with the cartridgethat is to say,in the groove of the end when a so-called headless shell is employed andwith the head when a headed shell is used. The hammer 5 is first thrownback to its cocked position, (shown in Figs. 2 and 4,) disengaging theshoulders 5 from the rear of the breech-block 4. The breech-block isthen opened by the operator taking hold of or when the breech-block isclosed, as shown in The piece 7 is provided with a hook I or shoulder ona projection 7, adapted to pressing upon the thumb portion 4 thereof. Inthe first portion of the opening movement of the breech-block the cam oreccentric 4 tends to swing the part 7 toward the rear of the firearm.The lower end of the part 7 is held from movement by the lower wall ofthe slot 7 engaging on the screw or pin 9 and also by the operation ofthe spring 8 on the fiat face 7. In the first stage of the opening ofthe breech-block the full power of the eccentric or cam 4i is exerted onthe cartridge to start it from the chamber in the barrel, and the firstportion of the movement of the extractor is a comparatively slow one.After the first starting movement the relative arrangement of the slot 7and the pin or screw 9 is shifted so as to allow the extractor-ejectorto turn on the cam. Then this stage is reached, the shoulder as on thebreech-block engages with the rear side of the wing of theextractor-ejector, and the continued movement of the breech-blockresults in throwing the face 7 out of engagement with the spring 8, andthe spring rests only on the corner between the faces 7 and 7 This isthe final stage of the slow or what may be termed extracting movement,and the position of the parts at this stage are shown in Fig. 2.Immediately following this stage the pressure of the spring 8 on thelower end of the wing of the ejector operates it rapidly from the po;

sition shown in Fig. 2 to that shown in Fig. 4, when the face '7 comesinto full contact with the spring 8. This movement is very rapid andresults in ejecting the shell with force. In this movement theextractor-ejector swings on the hub 4: as a pivot.

After the shell has been ejected a new cartridge can be inserted in thebarrel either with its head or end in rear of the back of the catchprojection 7 or in front of it. When inserted at the back, say-that isto say, completely or almost completely home in the chamber of thebarrel-the closing of the breech-block brings the shoulder y thereofinto engagement with the projection 7, moving the extractor-ejector inthe reversed movement from that heretofore described. As the back of theprojection '7 comes into engagement with the head of the shell it isthrown outwardly toward the sidethat is to say, toward the left as theparts are shown in Fig. 3-allowing the shoulder to pass the head or rimat the head of the shell. The spring of the washer portion 7 of theextractor-ejector allows this movement and immediately causes theshoulder of the projection 7 to engage back of the head or in the groovewhen it has attained the proper position.

What I claim as new, and desire to secure by Letters Patent, is-

1. A rocking cartridge-extractor having a shoulder to engage thecartridge, in combination with a pivoted breech-block having aneccentric on which the extractor is mounted operating to move theextractor rearwardly from the end of the barrel, and means fortemporarily holding the portion of the extractor below the eccentric andopposite said shoulder, substantially as set forth.

,2. The combination with the working parts of a firearm of the pivotedbreech-block having a cam-hub or eccentric-boss, a washer-like extractormounted upon said hub or boss having a shoulder to engage the cartridgeand the boss and extractor being arranged so that the cam or eccentrictends to move the extractor rearwardly with reference to the barrel, andmeans for temporarily securing the portion of the extractor oppositesaid cartridge engaging shoulder during the first movement of the cam oreccentr'ic,and aspring for rapidly operating said extractor in the finalmovement, substantially as set forth.

3. The combination in a firearm of the pivoted breech-block having aneccentric or cam hub arranged to throw toward the rear, the washer-likeextractor-' ej ector mounted on said hub having means for engaging withthe cartridge, means for temporarily securing the portion of theextractonejector on the opposite side of the hub from the point ofengagement with the cartridge during the first stage of the operation, ashoulder on the breech-- block for engaging and moving theextractorejector in a succeeding stage of the operation and a spring forgiving a quick, final movement to the extractor-ejector, substantiallyas set forth.

4. The combination of a pivoted breechblock having an eccentric-hubarranged to rock and throw from a point directly over the breech-blockpivot toward the rear, a washer like extractor-ejector mounted on saideccentric-hub and having means for engaging the cartridge and means fortemporarily securing the portion of said extractor-ejector opposite saidmeans for engaging the cartridge while said eccentric-hub is operating,a shoulder on the breech-block for engaging the extractorejector beforethe ejecting movement and a spring for giving a quick, final movement tothe extractor ejector, substantially as set forth.
